The extension is a straightforward wrapper to load Microsoft Copilot in a Chrome side panel. All permissions are necessary: sidePanel for the sidebar UI, declarativeNetRequest to selectively spoof Edge user-agent and allow iframe embedding, tabs to obtain active tab context, and notifications for unsupported Chrome versions. The code sends page content to Bing only when the Copilot shell requests it, which is its advertised purpose ('with context of the webpage you're viewing'). No unauthorized third-party endpoints, no obfuscation, no hidden data exfiltration. The ML model risk score is low (0.00), and the publisher has a trusted badge. The high risk-engine score is due to broad permissions, but they are legitimately used.
